Hidrogênio, carbono, nitrogênio e oxigênio em Steiner (2007)

Now let us look how the action of these so-called substances — which in reality are bearers of the Spirit — comes about in Nature. You see, that which works even inside the human being as oxygen and nitrogen, behaves itself tolerably well. There in the human being the properties of oxygen and nitrogen are living. One only does not perceive them with ordinary science, for they are hidden to outward appearance. But the products of the carbon and hydrogen principles cannot behave quite so simply. (Steiner 2007:26)
